My doodle ( who as severe allergies to grains, turkey, chicken + ) has been on this food for well over a year. Worked well for all his allergies, UNTIL recently. We noticed clumps of his hair & his incessant licking & red skin rash & that smell. After investigating, we looked up the ingredients again in his food. # 3 on the list? CHICKEN!!!! ( also Turkey Meal ! ) I called Castor & Pollux and was informed they added chicken in January 2017. We must have received one of the newer bags of food.
( there is a 2 year shelf life on the product ) Just got home from the vet with medicine, special shampoo & $ 200 later, we are back to square one. I encouraged the company to list ADDED CHICKENMy doodle ( who as severe allergies to grains, turkey, chicken + ) has been on this food for well over a year.

Dogs Hate This Food Now

Not sure what happened..formula change or what, but my guys do NOT like this.Most of the time they will eat most anything and they are leaving and walking away from about 1/2 their bowls. I've even mixed goodies up with it and they will eat around the food or lick the stuff off and spit out the food. I've fed it dry, soaked it, everything but do a wild dance to get them to like this, but no good:-( I've always liked this brand in the past. Oh well, off to try something else.

Our Basset, Wendell has a yeast problem. We have tried to find a grain free food that would help with this. We also wanted a food that was premium but wouldn’t break the bank! After several failed attempts we have settled on Castor & Pollux and it is definitely helping!

My dog won't touch it!

It's hard for me to rate this food fairly because while the ingredients are very top quality, my girl won't even touch this food...Oddly, we've tried this flavor combination in other brands with good success before.
We will be donating this bag to our local pet shelter!

First let me say Chewy is great. Their service and product line are tha best. I needed to switch my dogs’ food to a higher quality so I tried Castor & Polluck. Dogs love it and it’s good quality food. I use auto shipping and that has been such an easy way to go!

Great product, fast shipping

I love this product. My wheaten has skin allergies but when she started eating this food they went away. This food is hard to find. None of the stores locally carry it so I was happy to see I could order this on line. Thank you Chewy!

My dogs are gobbling it up

I like to feed different foods periodically and I always check Dogfood Advisor before I buy. This food gets the highest rating of 5 stars. It's a small kibble which is great for my 5 small older dogs, and there are bits of dried carrots and bananas for extra fun. I will buy this food again.

As a breeder, I did my own research on dog food in order to determine for myself what is the proper diet for our dogs and the puppies they have. I’m not one to simply believe that just because a government standard says something that it has my best interest, or that of my animals in mind.
In this case I believe my standards are higher and my research supports what I’ve chosen to feed my dogs.
What I determined with my research is we need to bare in mind the ‘natural ancestral’ diet of dogs which is high in protein and fat, plus they’d eat vegetables and fruits. Little or no grains were consumed as well as little in the way of carbohydrates.

I’m not one to simply believe that just because a government standard says something that it has my best interest, or that of my animals in mind.
In this case I believe my standards are higher and my research supports what I’ve chosen to feed my dogs.
What I determined with my research is we need to bare in mind the ‘natural ancestral’ diet of dogs which is high in protein and fat, plus they’d eat vegetables and fruits. Little or no grains were consumed as well as little in the way of carbohydrates. A dog’s ‘natural ancestral diet’ consisted of 56% protein, 25-30% fat, and 14% carbohydrates. This supports the need for a high quality meat-based protein as the #1 ingredient in a dog’s diet.
With the invention of dry dog food industry this changed to 18-32% protein, 8-22% fat, and 46-74% carbohydrates. The main reason being that carbohydrates and grains are cheaper than protein. Grains, especially corn should be avoided, but corn is one of the main ingredients in some dog foods because it’s cheap. The only grain I would even consider feeding my dogs is cooked brown rice.
It’s also important to understand that a dog’s energy comes from protein and fat and that source needs to be easily digested.
My ideal would be to feed my dogs a freeze-dried dog food mix that I add water, fresh meat, and bone meal to, but that is not within our budget to be able to do.
With Castor & Pollux Natural Ultramix Grain-Free Duck, Sweet Potatoes, & Peas I know I’m feeding my dogs a health diet. I love the fact that it has freeze dried pieces of fruits and vegetables in and that duck is the #1 ingredient as duck is easily digested and its nutrients available for quick absorption. Sweet potatoes are more nutritious and better for dogs than any other kinds of potatoes. I do not mind the fact that there are also other meat sources for the protein in this formula, as some are not digested and absorbed as quickly as duck, so I’m confident my dogs are receiving the energy benefits over a longer period between meals. My dogs are very active!
I greatly appreciate the fact that Castor & Pollux tests incoming ingredients as well as tests for quality and safety through the process as they make their dog food. I don’t feel I have to worry about any mishaps that could result in a harmful product being sent out.
It’s a highly nutritious dog food with 38% protein and 17% fat content as well as essential vitamins and minerals. With 6 dogs and the oldest being 11 years old with the least amount of activity, we just feed her less and she maintains a healthy weight. They love this blend and we couldn’t be happier.
If there is any negative part I have with it that would be that it has some chicken in it. I’m not a big fan of chicken in dog food, but trust Castor & Pollux with their testing of incoming ingredients.
I am also a firm believer that if your pet has an allergy to something you have to read the ingredients and not simply just rely on the name given the flavor of dog food. Since ingredients and ‘recipes’ can change it is also wise to check the ingredients periodically. Or, if there is a change in the appearance of the kibble in the bag read the ingredients.
I keep a copy of the ingredients from the dog food bag in my file for our dogs. This way, if there’s ever any question I have that on hand.… more
